Application filed January 22, 1912, Serial No. 672,595. Renewed May 15,1914. Serial No. 838,892.

To all whom' t may concern:

Be it known that I, HUGO L. PA'rzoLD, a citizen of the United States,residing' at Meriden, in the county of New Haven and State ofConnecticut, have invented certain which the following is ayspecification.

This invention relates to tires and a tire involving my invention can beemployed with advantage in connectionwith wheels of various kinds, butit is of especial utility when applied to an automobile wheel.

One of the objects of the invention is to provide a tire in sectionswhich can be readily and easily applied to and removed from a wheel, andalthough these sections may be of any suitable nature, ea'ch preferablyincludes in its make-up an inflatable member so that I can therebyobtain all the effects of the ordinary pneumatic tire. An inflatabletire is a desirable thing, but it is susceptible to puncture and whenthis occurs it is necessary before the tire can bev removed to jack upthe car. When an inflatable member is punctured and thereby deflated,this particular section can be removed without the necessity of jackingup the car and in a very simple quick manner. A tire embodying myinvention possesses many other features of novelty and advantage whichwith the foregoing will be set forth at length in the followingdescription wherein'I will outline in detail one of the several formsof- Referring to said drawings: Figure 1 is a side elevation of a wheelequipped with a tire involving my invention. Fig. 2 is a sectionalelevation of one complete segment and part of an adjacent segment. Fig.3 is a perspective view of the end portion of one of the segments. Fig.4 is a cross section on the line 4-4 of Fig. 2 looking in the directionof the arrow. Fig. 5 is a plan View of two adjacent segments, and, Fig.6 is a perspective view of a segment-carrier.

' Like characters refer to like parts throughout the several views whichit will be observed are on different scales.

In Fig. 1 of the drawings-I have shown a wheel l10, and this wheel maybe of any suitable nature, for instance such a one as is used upon anautomobile. vMy tire is preferably made in sections usually and as shownof segmental form, and there may be any desirable number of suchsections, for instance, and as illustrated, four, denoted respectivelyby 11, 12, 13 and 14. 1As already indicated the tire sections orsegments may be, of any suitable kind, although those represented are ofpneumatic type and each comprises an outer casing or shoe 15, and aninner' envelop or tube 16, the part-15 being usuallv made of canvas orother material such as Vis usually employed in making shoes of theordinary kind, while the inner infiatable member 16 is of rubber or someequivalent substance.

y Each segment or tire section is supported by a segmental carrierdenoted in a general way by 17, and although the said carrier may-be ofany desirable nature, it is represented as being ofsectional form beingcomposed in the present case, of substantially similar or duplicatesections 18 and 19 usually of metal and channeled or grooved as shown toreceive the beaded portions at the inner sides of the-respective shoes15. Owing to the fact that each segment-carrier is made in sections, itis an easy matter to connect or disconnect theA respective parts as willhereinafter more particularly appear. The segment-carriers 17 may beconnected with the wheel 10 in any desirable manner. Referring to Fig. 1itvwill be seen that each carrier 17 is provided at longitudinallyseparated points with clamping-members 20, thel members of which areadapted tov clamp the carriers to the rim of the wheel, it being evidentthat the radius of the inner surface of the carriers is the same asthatV of the rim of the Wheel. In Fig. 2 the carriers 17 are shownprovided with bolts 21 by which said carriers, canbe connected to therim of the wheel. f

Thev carriers 17 abut at their ends and while it is possible that thisabutting rela riers.k Each carrier is shown provided at its ends'withflanges 22 and 23, and thatflanges of the respective carriers areadapted preferably to fit flatwise againsteach other and to be alsocoupled together for instance by a tongue and groove joint, each flangeor cou-V pling head 22 being shown provided witha tongue or rib 24 toenter a complemental groove or channel 25 in the adjacent coupling heador flange 23 which thus provides a simple and effective means forlocking the carriers together. The plates or anges 22 f are relativelythin so as to secure a cer tain amount of resiliency orspringinesstherein, by reason of which said plates or flanges will be forcedsolidly against each other by the compressed air in the inflatablemembers 16 to thus aid in holding the tire in place. While the sectionsof each carrier 17 might be related vin any suitable way, l prefer topositively connect said sections, so that each tire-segment with itssupporting carrier presents an article of manufacture and by positivelyconnecting the sections of said carrier to each other, said carrier andits segment can be lhandled as a unit and applied to and removed fromthe wheel as such. ln the construction shown the section 19 of, eachcarrier 17 is provided with a spring latch 26, the shank of which may beriveted or otherwise suitably fastened thereto, and the active end orhooks 27 of which are adapted to enter seats or perforations 28 in thecompanion section 18 so as to thus securely connect the two sections ofthe respective carriers. By manipulating the latch it is a simple matterto separate the sections of a carrier, and when they are freed by theoperation of the latch,l they are slid longitudinally apart and itwillbe clear that when a segment is thus detached from its carrier, itbecomes a simple matter to substitute a new one therefor.

lt it a welLknown fact that when an inner tube of an ordinary tirebecomes deflated the outer tubeor shoe will flatten down, and in such anevent rim-cutting, as it is known, is the consequence. l provide meansfor positively preventing such result and various means may be providedtherefor. As represented l provide the carriers with anges which embraceor hug each shoe and hold it to such an extent when the inner` tubeis.deflated that said shoe cannot be flattened suiliciently to permitthe disadvantage in question, and while these flanges may be located atany suitable place upon the respective carriers 17 they are shownconnected with the plates or heads 22 and 23 being denoted by 29. ltwill be understood that in the construction shown Llerena there are twoside anges at each end of each segment, although in all cases, as willbe inferred from the observations already made, this is not essential.The coupling heads or plates 22 and 23 and the flanges 29 are not asdeep as the tire-segments so as not to eect the resiliency thereof.

Each inner member 16 is provided withk a nipple 31 which extends throughthe shoe 15, carrier 17 and rim of the wheel 10, and by which said1.member 16 can be inflated when desired. The end walls ofthe inflatablemembers 16 are materially thickened so as to electually resist thelongitudinal pressure of the air.

- rl`he shoes 15 at their ends are shown provided with blocks 32 whichare comparatively thick and which extend short of the inner portion ofthe said shoes. The inner tube unit 16 is incased is a canvas insert orjacket 34 between the two ends and side flanges or bodies of the casingunit 15 in order to prevent the inner tube 16 being thrust through the'gap or opening between the same, the terminal portions of said insertbeing denoted by 33. ll desire to call attention to the fact that saidblocks are free, by which ll mean that they are not conned vby anyclamping or equivalent means, so that when the inner tube becomesdeflated, these blocks are at once ready to exercise their functions ofcushioning the segment or equivalent. Therefore,in case a section as 16should become deflated on the road, and the automobilist or other personshould not have a new section he can safely get to a garage or otherplace, in that the ribs or blocks 32 act as cushions; this edect,however, can be otherwise obtained within the spirit of my invention. i

One of the blocks or ribs. 32 of each shoe 15 is shown provided with aprojection or bead 35 to enter an inner groove (formed by the tongue 24)of the adjacent coupling head '23, while the block at the other end ofsaid shoe has a channel to receive an internal projection (formed by thegroove 25) of the companion coupling head 22, by reason of which saidribs or blocks are interlocked with the respective coupling heads tothus limit lateral motion of the shoes. lt is necessary to also mentionthe fact that the strips 34 at the ends of which the flaps or tabs 33are situated, extend under the respective shoes 15.

From the foregoing description taken in connection with the annexeddrawing, itv will be clear that l provide a unitary device which can beapplied to and removed from a wheel as such. Said device comprises atire segment preferably inflatable and a carrier therefor, the carrierbeing provided with means independent of the wheel to which the unit isto be attached, for maintaining the unitary relation. ln the presentcase this carrier is in sections, the sections being adapted to clampthe segment, and the carrier being provided with means supported solelythereby for maintaining. the clamping relation.

What I claim is:

l. A tire segment and a segmental carrier therefor, in sections slidablyengaged with said segment from opposite ends thereof, said carrierhaving stop means against which the ends of the tire segment abut.

2. A tire segment and a segmental carrier therefor, in sections slidablyengaged with said segment from opposite ends thereof, said carrierhaving stop means'against which the ends of the tire segment abut, saidcarrier having a tongue at one end and a groove at the other end, bothextending radially or depthwise of said carrier, said tongue beingadapted to enter the groove in an adjacent segment, and said groovebeing adapted to receive a tongue on another adjacent segment.

.ably engaged with said segment from opposite ends thereof, said carrierhaving end v flanges against which the ends of the tire segment abut andalso having side flanges to engage opposite sides of said -tire segment.

4. A tire segment and a'segmental carrier therefor, in sectionslongitudinally slidably engaged with said tire segment from oppositeends thereof, said carrier having means to prevent relative endwisemovement of the carrier and segment and one section of the carrierhaving a latch and the other section thereof having a catch to'beengaged by said latch to therebyremovably hold the sections of thecarrier together.

In testimony whereof I affix my signature in presence of two witnesses.
